After I had been a few times and tried other brands considered, I decided on this purchase and the purchase has not regretted. The design of this e-cigarette like, it is relatively small and light, despite 1100 mAh battery! As "normal" heavy smoker - yet addictive! - Succeeds me now, cigarette consumption limit by around 75%, even on the road altogether. A filling and battery charge is sufficient for me two days, just fine to me. Of course there is a difference to the old smoke-cigarette, it should be able to get used to. The advantages are however obvious: less pollution, no smelly ashtrays, no stained curtains, and also in my local pub one does not mind. Now I'm going to try the best essences. I think it was a good decision.
